I NNOVATIVE S OLUTIONS IN S ENSORS AND C ONTROLS Product Bulletin 15AM Motor Protector/Thermal Cut-out As world market leader in appliance motor protection Texas Instruments builds the 15AM motor protector to meet almost any application in this field. The 15AM is designed to pro- vide locked rotor and overload pro- tection in a wide variety of motors for industrial and domestic appli- ances. The 15AM is the leader in the European AC motor protection market. Design & operating principles In the 15AM design the nickel plated shell holds and protects the inner components against varnish pene- tration and mechanical forces. The heart of the device is the calibrated Klixon™ bimetal disc, responding to current and temperature changes. It is supported by a slug and a contact welded on the disc. The fixed con- tact is placed on the opposite nickel- zinc coated plated steel shell, sepa- rated by a coated gasket for insulat- ing and sealing. The 15AM can be supplied as a basic device with leads and other integrated quick connectors or automated connection systems. Customized lead configu- rations are available on request. The 15AM can be fitted in the best possi- ble mounting location in combination with the optimum assembly opera- tion. As the 15AM is a metal device it may be necessary to insulate the device from other conductive parts, an insulating sleeve is available on request. The operating principle of the 15AM is both simple and effective. A cur- rent flows through the resistive Klixon™ bimetal disc. When a fault condition occurs, the increased cur- rent and shell temperature heats up the bimetal disc which opens the contacts. As the device cools down to a safe temperature, the contacts will automatically reset.
Applications
The 15AM operates as an incorpo- rated thermal sensitive protector in electric motors for pumps, washing machines, dish washers, dryers and in several other applications like vacuum cleaners, fans, battery chargers, transformers for lighting (EN 61558) and microwave ovens. Key Benefits
